Joined here about a year ago, have just moved south (to Chelmsford) and I'm going to be building my first fixed gear soon (sounds like a FisherPrice toy?!).
Anyway, I've just picked up a cheap Peugeot frame on eBay (after my last got wrecked by a car), so hopefully I should have something to show for my efforts soon!
Welcome, Ben, have a look here:
